Marine renewable energy sources such as wave and tidal power are poised to become an important part of the U.S. future clean energy mix. Recent Electric Power Research Institute (EPRI) and Georgia Institute of Technology studies have measured the annual technically recoverable energy from U.S. wave and tidal resources at 1,170 terawatt-hours (TWh) and 66 TWh respectively–a significant proportion of the 4,000 TWh of U.S. electricity demand. In practice, the realities of project development likely will result in a much smaller realized resource, but if 10 percent extraction can be reached, this would be equivalent to the output of 37 large fossil fuel plants.
